"Tonsil Eye 'Tis" has to be one of the wackiest ideas for a story. It's by Australian Author, Paul Jennings...

Our hero's girlfriend gives him a garden gnome, which he hates. He is smashing up the gnome when he finds it has a tiny face inside its mouth. The little face flees the mayhem and takes up residence on our hero's tonsils. He can see it because he grows an EYE on his INDEX FINGER and can put it down his throat to look.

The story winds along in its weird and wonderful way, reaching, strangely enough, a happy ending.

Very cool... I'd love to have an eye on my finger.

But I think it would cause all kinds of problems too... Like, people could easily look through holes at things they shouldn't be seeing. And because we use our fingers for work all day, it would be at risk of infection and damage (imagine bashing your eye on a computer keyboard at 77 wpm!!!)

That's a great idea, although it's not a new one. I first heard this idea presented by Festus Hagan (Ken Curtis) on Gunsmoke sometime in the early 1970s. He figured it would be great for "peepin' around corners and such". He also thought it would be good to have your mouth on top of your head so if "you was runnin' late, you could just put your breakfast in your hat and eat it on the way".
As usual, Doc (Milburn Stone) disagreed on both counts.
